Open channel analysis with 2009 Flow Simulation

I'm a newbie to 2009 Flow Simulation and am trying to evaluate models under partially submerged, gravity flow conditions - i.e. open channel flow. We bought this software with the understanding that this type of analysis was possible. However, when I set up the boundary conditions the thing runs as if the model is fully submerged regardless of flow. All of the tutorials and examples I've seen so far only address systems flowing full. I found one post that seemed to indicate others having trouble resolving a water/air interface with 2008 FloWorks. Can 2009 Flow Simulation do this somehow?
